Default motor mounts

Have been working on this thing myself for a while, finally got some help. Right side mount is bad. Not sure about the front and rear tranny, will be digging in deeper there tomorrow. I can;t really determine what is what on gmpartsdirect and advance'* site lists solid and hydraulic ($$$). Which do I want and does anybody have part numbers for all three? BTW, what the heck is the dog bone and where does it mount?

The dogbone mount is the right rear motor mount. I would call it neither solid nor hydraulic. It has rubber bushings.

Yup. It'* attached to the output housing of the trans and the frame. Looks just like a dog bone.

The front and rear mounts on the driver'* side are the mounts that failed on mine.

Aye, the Torque Axis Mount it the one on the right side on top, It rarely goes out.

The Front Transmission Mount is the one I delt with for months, going to a solid mount then finally a 94 mount. There'* only one change to make, You need a longer bolt to hold the mount+tranny to the engine. Got mine from the junkyard.

The Rear Transmission Mount is the hardest to change as you have to get it over the sway bar, under the steering rack and jammed under the transmission, This one is likely blown.

The dogbone or right rear mount is only visible from the bottom, Would be easy to change but the lower bolt goes in the wrong way, you'll see what I mean. The front left mount being blown will make this one die inside a week.

Tranny is coming out very soon for repairing the TCC solenoid and (ahem) shift kit. Once they have it out, it should be simple for them to replace the mounts. I'm thinking I might as well do the other two atthe same time, depending on cost.

Can somebody verify the part numbers for me?

22112485 Torque Strut
22175156
17996749
22145387 front tranny
22146628 Engine mount
22188869 Rear Trans mount

These all seem to be right, But I can't find why there are three numbers for the torque strut... I know some 92'* got a different length one, But I can't find which is which.

Thanks Dame. I was over at my tranny mech'* place again today. We had the old girl up on the rack checking things out. Front tranny mount is broken. Rear is on the way. Material in the dogbone is all squished out and the material in the dampner is all nice and cracked. They had 2 of the four, ordered the other two (newfound discount for me). I also ordered the control arm bushings today. She goes under the knife next Friday, tranny coming out, new mounts, control arm bushings, and that brand spanking new shiny SK-4T60e Jr shift kit that was sitting on the bench this afternoon with my drool hanging on it!

Not only are they putting in the kit, but letting me play on my girl while she is on the rack! Which should I be more excited about: the shift kit, or working on my car without breaking my back?

Anybody have the jig for the control arm bushings, either prefabbed or homemade that I can borrow? If not, I can piece one together but I know I am gonn ahave to mnake several trips to the hardware store to get it right (just the way my luck runs).

Why change out the control arm bushings? You got a dead one?

Look worn, one side has some slop, going to be real easy access, and cheap. Besides, that will just leave the sway bar bushings (not links) that will be old, and they look almost new.
